To aZZ wiiom it omy 0011mm:

Be it known that l, linnnn'r l VAnn FAT-Tl- SON, a citizen of the United States, residing in the city of'Lockport, in the county of Niagara, in the State of New York, have invented certain new and 'uscfu'l improvements in a Burner, of which the following is a specification.

This invention relates to hydrocarbon burners'and its principal object is to provide an economical burner of a type suitable for domestic use, and of such improved construction as to practically eliminate the usual difiiculties encountered under domestic conditions, such as the danger of explosion, smells from burning oil carbon deposits which clog up and insulate heating surfaces or complicated mechanism which. cannotbe operated by any one but persons 7 familiar with mechanics.

Other more specific objects or" the invention, as well as the construction and er termediate portions rangenoent"oi parts constituting the embodiment herein disclosed wi l be more readily understood from the followi 'descrio 'on and accompanying drawings; Lil. which lat ter: I

Fig. 1 is a side elevation of my improved burner with parts broken on i Fig. 2 is a plan view par Fig. 3 is a vertical sect pa at of the burner.

' Fig. 3k is a transverse sectional wire; of the base plate, and Fig.'- is a view of a detail.

i in these drawings, the numeral ecsig nates a rcctangularbase plate 3 =roi' il with an upstanding marginal lhmgz c 2 -.icndi-ng' entirely around the edges oi ti =.zrte and v with inl ght than. the remainder of the flange. .elt each corner of the plate and within the marginal flange 2 there is provided an apm'ture iiillll'tlllillfil'l by an upstanding: ring shaped wall 5. oi which the flange 2 army he said to constitute a part and each wall terms a. socket in which is inserted the lower end of one oi a plurality of air conduits 6. The conduits l3 arc arched upwardly and inwardly, as shown, and converge toward an. integral central portion '2, overlying i re center oi the base plate 1 and provided with a bottom opening 8. The base plate is 'l'urhcr prothe sides of said ill v' led with a central upstanding circular I e 9-integrally connected t6 the side .nrtions of the flange 2 by the webs l0 and The web ll is of greater height than he web 10 and is provided with a relatively ar e bore 12 through which the water suppipe is adapted tobe passed, as will he a'ter understood. The web 10 is provided with a smaller bore 13, which serves as an overflow outlet for surplus oil entrapped bet een the flanges 2 and 9.

A circular marginal wall or casing designet-ed generally by the numeral 14 is adapted 19, fornied in the base. The upper end of the nozzlefZO projects upwardly through an opening 21 in the lower wall 15, and is 0 smaller diameter than said opening so as to provide an intervening passageway. The opening 21 leads from the interior of the casin M to the substantially frusto conical in' chamber 22 above said openin This chamber is epen at its upper end and is provided with a shoulder 23 surrounded by an annular flange 24. A plate partially closes the upper end of this chan'iher and is provided with a central aperture 26 and adjacent its periphery.with a depending flange 527, which is supported upon the shoulder 23-3 and engages the inner side of the flange 24-, The plate 25 is integrally provided on its upper surface with four equidistu lily spaced ribs 28 having upwardly projecting tongues 29 entering suitable openings 30 provided therefor in a spreader plate 31, the plate being supported by the ribs. A heeded bolt 32 passes downwardly through the central portion oi the spreader plate 31 and has mounted thereon beneath said plate two seats of mixing vanes designated ntil i, and 3% respectively. 'lt will be noted that the vanes oi' the upper sot being located in the widest portion oi. the mixing chamber it? are made longer than the vanes of the lower sci in each instance, the vanes radiate chambers 39 and '40.

from a central hub portion 36 encirclin the bolt 32. Thehubs 36 are spaced apart y a short sleeve 37, the lower vane is supportedby the nuts 38. Encircling the upper end of the mixing chamber 22 are a pair of superimposed water coils or steam generating The upper coil or generating chamber 39 is provided with a air of outwardly and downwardly extending cars 41 formed integral therewith, and elbows connected to the upper ends of a pair of vertical pipes 42. The lower ends of said vertical pipes are connected by nipples 43, to the outer ends of a pair of horizontal pipes 44. The inner ends of pipes 44 are in turnconnected to extensions 45 formed integral with the upper wall 15 of the casing 14. The lower coil or gei1erat.

- ing chamber 40 is suspended from-the upper chamber 39 by means of the conduits 46, which establish communication between the two chambers. The conduits 46 are diametrically opposite each other and spaced apart fromthe ears 41. This lower coil or generating chamber 40 is providedwith a pair of water inlets as indicated at 47 and when disposing the casing '14 within the flange 9, one of these inlets is plugged and the other is disposed above the bore 12 of the web 11, so as to be conveniently secured to a water supply pipe 48 extending upwardly throu' h said bore. The numeral 49 indicates a pi ot burner of conventional construction. I

In the operation of the burner, oil is fed by gravity to the nozzle 20 through. theeentral opening 19" and the nipple 19 and passes through said nozzle into the mixing chamber 22. Water is supplied to the lower generating chamber 40 and is discharged from the upper generating chamber 39 in the form of steam which is conducted to the casing 14 and passes from said casing into the mixing chamber'22 through the passageway provided between the Wall of the opening 21 and the nipple 20. The passage -of the steam into the mixing chamber 22 around the nozzle acts by suction to draw the oil through said nozzle and during passage of the oil and steam toward the upper end of the mixing chamber, the vanes 33 and 34 located in said chamber cause the oil and steam to become thoroughly mixed before 'being'discharged outwardly through the'openings-provided between the ribs 28. The mixture'is ignited as it is discharged from the mixing chamber, the plate serving to spread the flame, and combustion of the same being aided by air conveyed through the conduit 6 and discharged through the opening 8, which opening, it will be noticed is located immediately adjacent the point of combustiom The heat developed bythe combustionlof the gas serves to convertthe watermthe chamber 39 into stcaln which is steam into the lowerend of 130 subsequently mixed with the oil in forming the combustible gas.

now consider to be the preferred embodiment of my invention, it is to be understood that 1 do not limit myself to the exact construction or arrangement of parts set forth, but that I reserve the right to resort to such changes and modifications as come within the scope of the appended claims, and do not depart from the spirit of the invention.
